Abstract

Methods and apparatus to provide loop parallelization based on loop splitting and/or index array are described. In one embodiment, one or more split loops, corresponding to an original loop, are generated based on the mis-speculation information. In another embodiment, a plurality of subloops are generated from an original loop based on an index array. Other embodiments are also described.
